Question

Look at the diagram showing hydrochloric acid being added to water. mc006-1.jpg mc006-2.jpg

Which statement best explains what is taking place?
A strong acid is disassociated completely, producing more conjugate base.
A strong base is disassociated completely, producing more conjugate acid. Hydrogen is combining with chlorine to form more acid.
Hydrogen is combining with chlorine to form a strong base.

Answer 1

the answer is A......

Answer 2

Answer: Option (a) is the strong acid.

Step-by-step explanation:

Hydrochloric acid is a strong acid and when it is added to water then the following reaction takes place.

`HCl + H_(2)O \rightarrow H_(3)O^(+) + Cl^(-)`

where,
`H_(3)O^(+)` is a conjugate acid and
`Cl^(-)` is a conjugate base.

Therefore, when we add HCl into water then it dissociates completely into hydronium ion and chlorine ion.

Thus, we can conclude that a strong acid is disassociated completely, producing more conjugate base.
